ClinConnect Summary

This clinical trial is studying a new test called the Quantra® hemostasis analyzer, which helps doctors monitor blood clotting in patients undergoing heparin therapy for conditions like venous thromboembolic disease (a type of blood clot). The trial aims to see if this new test can provide better information about how well a patient's blood is clotting compared to standard tests. The Quantra® analyzer uses ultrasound technology to assess the properties of blood during the clotting process and can be used right at the patient's bedside, making it quicker and easier to get results.

To participate in this trial, you need to be over 18 years old, be receiving heparin treatment, and have a doctor who has ordered a specific blood test called anti-Xa activity. The trial is open to everyone regardless of gender, but pregnant or breastfeeding women, as well as those who cannot provide consent or are receiving other blood-thinning medications, cannot participate. If you join the study, you can expect to have your blood tested using this new analyzer, and your results will help researchers understand if this method is effective for managing blood clotting in patients receiving heparin.
